Thank you both for the replies and info. I saw that H&W ER photo before. The levers with the locking thumb screw was the model for my levers. It's amazing that there's so much more to notice, especially with the help of others.

I'll definitely have to redo those telegraphs. The conduit path has really stuck in my craw. I just had to revisit the Britannic plans again.

We know the path from under the bridge forms a single conduit going Aft along the ceiling of "A" deck, about amidship. We know it must turn somewhere else it run straight through boiler casings, stair cases etc.

We also know the path leads to two areas: the reciprocating room and aft docking bridge.

Bill commented about my previous routing, that the top winches over the cylinder heads get in the way. That's right and is why I didn't run them to the ceiling.

So below is my proposal. There is no scale to the drawing. It goes aft from the bridge and down BR 5&6 casing or down its fidley way. It desends down to the floor level of "D" deck. Then turns Starboard (or Port) and runs under the floor just outside each casing. There may be maintenance hatches at each casing with a roller/pulley to compensate for the curving length of the decks. That position also allows it to miss all obstacles including stair cases.

In the case of the ER cables, they turn amidship just after the ER casing then down to the ER floor and then distributed among the telegraphs. The telegraphs could be placed almost anywhere in the room without much obstruction.

The docking bridge cables could continue aft as they go.

I came to this very possible routing which I am confident of. Especially after seeing the other H&W ER photo, particularly how they joined the two conduits and went straight up. I previously thought those conduits were some kind of catwalk support!

I have next week off my regular job and hoping to get most of this done. Thanks!
